No recall, as Recalls are for safety related problems.
ON diesel engines from July 1992 thru April 1994(production) MB installed timing chains that didn't last long (sub-standard quality) so they issued a service bulletin to that effect. Most of the substandard chains BROKE between 30K & 75K miles. IF your car was produced between those dated then HAVE the cam timing checked. SI number 05/93 dated Nov 1995.
